Specification of Letters Patent.

Patented J an. 6, 1914;

Application filed December 26, 1912. Serial No. 738,669.

To all 'll'llfllil it may concern Be it-known that I, PAUL Annon, residing at Tulsa, in the county of Tulsa and State of Oklahoma, a citizen of the United States, have invented or discovered certain new and useful Improvements in Rope- Clamps, of which improvements the follow ing is a specification.

ln drilling gas and oil wells, the movement of 'the drill is etl'ectedby a walking beam or other suitably.reciprocating means, which is connected to the rope extending down into the well by a temper screw and clamps. In addition to the drill other tools for straightening and cleaning the well must lie-connected to the operating means from time to time. As the drill and the parts connected thereto are much heavier than thcother devices it is desirable to use smaller ropes for the sand pumps, etc, than is required for the drill and the parts connected thereto. The clamps heretofore used have grooves for the large or drill rope, and hence such jaws must be removed and others substituted when smaller ropes are used.

The invention described herein has for its object the piiovision of jaws having a plurality of grooves varying in size thus permitting: of the same jaws being used in connection with the various tools or implements used in drilling=a well.

The. invention is hereinafter more fully described and claimed.

In the. accompanying drawing forming a part of this specification, Figure 1 is a top plan view of a clamp having my improvements applied thereto; Fig. 2 is a. side-elevation of one of the parts of the clamp. and Figs. 3 and 4 are detail views of one of the removable jaws.

The clamp consists of two parts or members 1 pivotally connected. at one end and provided at their opposite ends with suitable means whereby said pa rt-s can be drawn together. A suitable COIiStllK'tlOli for this puroose consists of a threaded rod 2 so pivot-e to the end of one ofthe parts 1, that it can be swung into and out of a notch in the other part, and a nut 3 mountedon said rod and adapted to bear against bothportions forming the side walls of the notch in the second member. Each part'orlneinb'er is provided with suitable means as the links 4 whereby it may be eonnectedtothe'temper screw. The inner faces of the part's'orf, members are recessed for the receptionof' the jaws 5 in both sides'o'f'which are formed grooves 6 varying intransverse dimensions for the receptionof different sidesa's are" required in drilling wells. Ithasbeen found that the grooves in clamps are":

idly worn in use, and by formin t-hen'r' oh an easily removable portion f t 1- only such part requires replacement. when the grooves are worn. And furtherTby forming these" renewable arts with a" plu ,to 'en' ageropes' rality of grooves" adapt'e varymgan diameter, the several operations involved in drilling can be carried'without any change of clamps or jaws. As clearly;

shown, the rope holding grooves .arefonned in both faces of the removable jaw, which; 15 provided at its upperend with lugs 7,; '75

which extend into notches 8 in the sidewalls of the parts or members 1, so as to retain" the jaws in position in the'recesses. While not essential, it IS preferredthat the notches' sliml'ld be made with an angular extension intoovhich the lugs may'passwhen being;-- placed in position, so thatthejaws'willbe' held securely in their recesses. lhe"lugs'onthe jaws and the notches in 'the'side wallsthan half the diameter ofthe rope'tobe' gripped so that the jaws can sofirmly clamp the rope that. the latter cannot slip through them during the drillingoperation.

T claim herein as my invention:

rope clamp having in combination two arts or members pivotally connected at'on'e end, and having recesses formed in their inner faces, said recesses having their side yells notched, mean s'for drawing the parts or members together and reversible jaws my hand. havifig grooves of dlfierent transverse dipgs adapted to engage said notches in the Wiiznesses: s1

inensions in bothfaces, and provided with ARBON' 5 members.
